Association of Blood Pressure at Specific Time-Points with 1-Year Renal Outcomes in Patients with Diabetic Chronic Kidney Disease.
Article in Electrolyte & blood pressure : E & BP, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe 24-hour mean blood pressure (mBP) is the best predictor of organ damage; however, it is not easily applicable in clinical practice. The APrODiTe study suggested that systolic blood pressure (SBP) values at 7:00 AM and 9:30 PM were associated with the 24-hour mSBP in patients with chronic kidney disease (CKD). We investigated the association of the SBP values at these time-points with the renal outcomes in patients with diabetic CKD during 1-year follow-up.
methodsNinety-six patients with diabetic CKD were included at 1-year follow-up. The renal outcomes were an increase in the random urine protein/creatinine ratio or estimated glomerular filtration rate (eGFR) deterioration, which means a decrease in eGFR ≥5 mL/min/1.73 m
resultsThe baseline SBP values at 7:00 AM, and 9:30 PM, and the 24-hour mSBP were 135.6±24.9 mmHg, 141.7±25.6 mmHg, and 136.4±20.7 mmHg, respectively. The SBP values measured at the same time-points after 1 year were similar to those at baseline. The SBP at 7:00 AM was significantly associated with eGFR deterioration in the univariate and multivariate analyses (odds ratio [OR]: 1.032; 95% confidence interval [CI]: 1.006-1.059; p=0.016). The SBP at 7:00AM and 24-hour mSBP did not show a concordant association with sustained proteinuria in the linear and logistic analyses. In the subgroup analysis, the association between the SBP at 7:00 AM and eGFR deterioration persisted in patients with CKD stage 3-5 (OR: 1.041; 95% CI: 1.010-1.073; p=0.010).
conclusionThe SBP at 7:00 AM, in addition to the 24-hour mSBP, is also associated with eGFR deterioration in patients with diabetic CKD, particularly in those with CKD stage 3-5.
